Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a radiator with adjustable heat dissipation. Background Technology

[0002] During the manufacturing process, the electronic control devices and other electronic components inside air conditioners require reliability testing to determine product performance. During testing, these electronic products rely on heat sinks to control heat dissipation, cooling power devices or other areas requiring cooling. The heat dissipation capacity of the heat sink directly impacts the operational reliability of the electronic product and the accuracy of the testing. However, traditional heat sinks are often made from a single piece of aluminum, resulting in a solid internal structure. This solid structure makes them heavy, and their fixed design prevents adjustments to the heat dissipation based on the amount of heat generated by the test target or object.

[0003] This design limits the flexibility and adaptability of the heat sink to some extent, especially during thermal reliability testing of power devices or other areas that require cooling, where the limitation of not being able to adjust the heat dissipation is particularly evident.

[0004] Therefore, existing heat sinks need to be improved to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a heat sink with adjustable heat dissipation. This heat sink can adjust its heat dissipation capacity by adjusting the number of fins in the snap-fit ​​position, thereby meeting the usage requirements of different occasions. This design is particularly suitable for thermal reliability testing of electronic products, and helps to improve the accuracy of thermal reliability testing.

[0006] A heat sink with adjustable heat dissipation includes a bracket and a fixing clip, the fixing clip being snapped onto the bracket; the bracket is provided with a plurality of first slots, the fixing clip is provided with a plurality of second slots, the first slots and the second slots correspond to each other, and a snap-fit ​​position is formed between the first slots and the second slots;

[0007] Fins, wherein the fin snap-fit ​​position is located in the snap-fit ​​position.

[0008] The fins are fixed in the snap-fit ​​positions formed by the first and second snap-fit ​​slots using a snap-fit ​​mechanism. Users can add or remove the number of fins as needed. By adjusting the number of fins in the snap-fit ​​positions, users can adjust the fins according to the amount of heat generated by the object under test, thus flexibly adjusting the heat dissipation of the radiator. This radiator design is suitable for various applications, especially thermal reliability testing, and can provide suitable heat dissipation conditions according to different test requirements. By precisely controlling the heat dissipation according to actual needs, it helps to improve the accuracy of the product in thermal reliability testing and ensure the reliability of the test results.

[0009] In a preferred embodiment of this utility model, the bracket includes a base plate and connecting arms. Two connecting arms are provided, which are disposed opposite to each other on both sides of the base plate. A plurality of first slots are provided on the base plate and located between the two connecting arms.

[0010] Two connecting arms are positioned opposite each other on both sides of the base plate, providing mounting positions for the fixing clips and the fins. The first slot is located between the two connecting arms; this layout facilitates the rising of hot air and the sinking of cold air, creating effective natural convection and improving heat dissipation efficiency. Furthermore, the multiple first slots distributed between the two connecting arms help to evenly distribute heat and prevent localized overheating.

[0011] In a preferred embodiment of this invention, each connecting arm is provided with a locking groove at its top, and a locking block is provided on the fixing clamp. The locking block is adapted to the locking groove, and the fixing clamp is engaged with the bracket through the cooperation of the locking block and the locking groove.

[0012] The locking groove and locking block design simplifies the installation and removal of the clamp. During use, operators can easily snap the clamp onto the bracket without additional tools or complicated operations, improving installation efficiency and user experience. Furthermore, this design facilitates daily maintenance and cleaning, helping to extend the radiator's lifespan.

[0013] In a preferred embodiment of this invention, each connecting arm is provided with a plurality of flow guide grooves, and the opening on one side of each flow guide groove faces the snap-fit ​​position.

[0014] The design of the airflow channels helps guide airflow, especially towards the snap-fit ​​area, i.e., the area where the fins are located. This layout increases the airflow area around the fins, thereby improving heat exchange efficiency and enhancing the overall heat dissipation effect of the radiator. The airflow channels also reduce the generation of localized hot spots during radiator use; this uniform airflow distribution improves the heat dissipation efficiency of electronic components.

[0015] In a preferred embodiment of this invention, a partition is formed between two adjacent guide channels, and the partition is provided with the locking groove.

[0016] The locking grooves on the partition provide more positions for the installation of the fixing clips, thereby making the heat dissipation range of the radiator more adjustable and applicable to more occasions.

[0017] In a preferred embodiment of this invention, the base plate is provided with cooling holes, which correspond to the first slot and penetrate the base plate along the length of the first slot.

[0018] The design of the cooling holes corresponding to the first slot effectively guides airflow and creates good airflow circulation. The introduction of cooling holes effectively reduces the temperature of the base plate and surrounding area, thereby improving the heat dissipation capacity of the radiator.

[0019] In a preferred embodiment of this invention, the base plate is provided with a plurality of screw holes, which are located at the edge of the base plate and on one side of the connecting arm; the edges of the screw holes are chamfered.

[0020] Screws are used to secure the radiator. The screw holes are located on the edge of the base plate and close to the connecting arm. This helps to evenly distribute the force on the base plate when fixing the radiator with screws, enhancing the overall structural stability of the radiator. The chamfered design reduces stress concentration at the screw hole edges, preventing material fatigue or damage caused by stress concentration and extending the radiator's service life.

[0021] In a preferred embodiment of this utility model, a plurality of fixing clips are provided on the bracket, each fixing clip including a clip bar and a plurality of protrusions. The plurality of protrusions are arranged on the clip bar along the length direction of the fixing clip, and a second slot is formed between two adjacent protrusions. The cross-sectional area of ​​the protrusion on the side away from the clip bar is smaller than the cross-sectional area on the side closer to the clip bar.

[0022] By incorporating multiple protrusions on the fixing clamp, the contact area with the heat dissipation fins can be increased, thereby improving the fixing stability of the heat dissipation fins and ensuring that the fins will not loosen or fall off under various operating conditions. Furthermore, the cross-sectional design of the protrusions facilitates fin installation.

[0023] In a preferred embodiment of this invention, multiple arc surfaces are provided on both sides of the fin along the direction from the first slot to the first slot.

[0024] The curved surface design increases the surface area of ​​the fins, thereby increasing the area in contact with the air. This helps to enhance heat exchange efficiency, allowing heat to be transferred from electronic components to the fins more quickly and ultimately dissipated into the environment. Furthermore, the curved shape helps optimize the dynamic characteristics of airflow through the fins, reducing airflow resistance and allowing air to flow more smoothly over the fins, thus improving heat dissipation efficiency.

[0025] In a preferred embodiment of this utility model, a fixing surface is provided at the junction of the fin and the first slot, and at the junction of the fin and the second slot, and the fixing surface is a plane;

[0026] A heat dissipation pipe is provided in the first slot, and the heat dissipation pipe is snapped into the first slot to limit the position of the fins.

[0027] By setting a fixing surface at the junction of the fins and the slot, the contact between the fins and the slot can be made more stable, reducing fin displacement caused by vibration or thermal expansion and improving the overall stability of the radiator.

[0028] The heat dissipation pipes are snapped into the first slot, limiting the position of the fins and ensuring that they do not shift or fall off during use. Furthermore, air can circulate within the heat dissipation pipes, which improves the heat dissipation capacity of the radiator.

[0029] The beneficial effects of this utility model are as follows:

[0030] This utility model provides a radiator with adjustable heat dissipation, comprising a bracket, a fixing clip, and fins. The fixing clip is snapped onto the bracket; the bracket is provided with multiple first slots, and the fixing clip is provided with multiple second slots. The first and second slots correspond to each other, and a snap-fit ​​position is formed between the first and second slots; the fins are snapped into the snap-fit ​​position. In practical applications, both the bracket and the fixing clip can be made of metal, which gives them excellent thermal conductivity, allowing them to act as heat dissipation components in the radiator, thereby improving the overall heat dissipation capacity of the radiator. The fins are fixed in the snap-fit ​​position formed by the first and second slots by snap-fit, and the user can increase or decrease the number of fins as needed. By adjusting the number of fins in the snap-fit ​​position, the user can add or remove fins according to the amount of heat generated by the object being measured, achieving flexible adjustment of the radiator's heat dissipation. This heat sink is particularly suitable for thermal reliability testing of electronic products and power devices. It can provide suitable heat dissipation conditions according to different test requirements. When the heat generated by the test product is large, the heat dissipation of the heat sink can be increased by adding fins; when the heat generated by the test product is small, the heat dissipation of the heat sink can be reduced by reducing fins. This helps to improve the accuracy of the product in thermal reliability testing and ensure the reliability of the test results. Attached Figure Description

[0040] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0041] During testing, electronic products require heat sinks to control heat dissipation and cool power devices or other areas requiring cooling. The effectiveness of the heat sink directly impacts the reliability of the electronic product and the accuracy of the test. However, traditional heat sinks are often made from a single piece of aluminum, resulting in a solid internal structure. This solid structure makes them heavy, and their fixed design prevents adjustments to the heat dissipation based on the amount of heat generated by the test target or object.

[0042] This design limits the flexibility and adaptability of the heat sink to some extent, especially during thermal reliability testing of power devices or other areas that require cooling, where the limitation of not being able to adjust the heat dissipation is particularly evident.

[0043] Based on this, this application provides a heat sink with adjustable heat dissipation.

[0044] Example 1

[0045] like Figures 1-7 As shown, this embodiment provides a heat sink with adjustable heat dissipation, including a bracket 1 and a fixing clip 2, the fixing clip 2 being snapped onto the bracket 1; the bracket 1 is provided with a plurality of first slots 15, the fixing clip 2 is provided with a plurality of second slots 24, the first slots 15 and the second slots 24 are corresponding to each other, and a snap-fit ​​position is formed between the first slots 15 and the second slots 24;

[0046] Fin 3, wherein the fin 3 is snapped into place in the snap-in position.

[0047] Specifically, bracket 1, as the main body of the radiator, provides a location for the installation of fins 3 and fixing clips 2. It should be noted that after the fixing clips are fixed on bracket 1, they must be able to withstand the force of external forces to ensure the structural stability of the entire radiator.

[0048] The first slot 15 and the second slot 24 can have the same or different shapes, and their cross-sectional dimensions can be the same or different. In practical applications, the cross-sectional shapes of the first slot 15 and the second slot 24 can be rectangular, U-shaped, or dovetail groove designs. When the cross-section of the first slot 15 is a dovetail groove, the narrow end of the dovetail groove can be designed to match the thickness of the fin 3, while the wide end provides sufficient space, making the fin 3 easy to install and providing more airflow area, thus improving the heat dissipation capacity of the radiator.

[0049] In practical applications, the aforementioned adjustable heat sink utilizes metal for both the bracket 1 and the fixing clip 2, providing excellent thermal conductivity and enabling them to function as heat dissipation components, thus enhancing the overall heat dissipation capacity. The fins 3 are fixed in the snap-fit ​​positions formed by the first snap-fit ​​slot 15 and the second snap-fit ​​slot 24, allowing users to increase or decrease the number of fins 3 as needed. By adjusting the number of fins 3 in the snap-fit ​​positions, users can adjust the fins 3 according to the amount of heat generated by the object under test, achieving flexible adjustment of the heat sink's heat dissipation. This heat sink is particularly suitable for thermal reliability testing of electronic products and power devices, providing appropriate heat dissipation conditions based on different testing requirements. When the heat generated by the test product is high, increasing the fins 3 increases the heat dissipation; conversely, decreasing the fins 3 reduces the heat dissipation, helping to improve the accuracy of thermal reliability testing and ensuring the reliability of test results.

[0050] Example 2

[0051] This embodiment is an improvement on embodiment 1.

[0052] In this embodiment, the specific structure of the support 1 is provided as follows:

[0053] like Figures 1-7 As shown, the bracket 1 includes a base plate 11 and connecting arms 14. Two connecting arms 14 are provided, and the two connecting arms 14 are arranged opposite to each other on both sides of the base plate 11. A plurality of first slots 15 are provided on the base plate 11 and located between the two connecting arms 14.

[0054] In practical applications, the connecting arm 14 can be machined on the bracket 1 by a machine tool. The connecting arm 14 and the base plate 11 can be integrated to ensure the structural stability of the entire bracket 1.

[0055] The connecting arm 14 protrudes upward from the surface of the base plate 11, providing a mounting position for the fixing clip 2 and also a mounting position for the fins 3.

[0056] The first slot 15 is located between the two connecting arms 14. This arrangement facilitates the rising of hot air and the falling of cold air, forming effective natural convection and thus improving heat dissipation efficiency. Moreover, the distribution of multiple first slots 15 between the two connecting arms 14 helps to evenly distribute heat and avoid localized overheating.

[0057] Example 3

[0058] This embodiment is an improvement on embodiment 2.

[0059] like Figures 1-7As shown, in this embodiment, each of the connecting arms 14 is provided with a locking groove 141 at its top, and a locking block 22 is provided on the fixing clip 2. The locking block 22 is adapted to the locking groove 141, and the fixing clip 2 is engaged with the bracket 1 through the cooperation of the locking block 22 and the locking groove 141.

[0060] The design of the locking groove 141 and locking block 22 simplifies the installation and disassembly process of the fixing clip 2. During use, operators can easily snap the fixing clip 2 onto the bracket 1 without additional tools or complicated operations, which helps improve installation efficiency and user experience. Moreover, this design facilitates daily maintenance and cleaning, helping to extend the service life of the radiator. Because the fixing clip 2 and the bracket 1 are tightly connected through the locking mechanism of the locking groove 141 and locking block 22, the radiator can maintain a stable structural state during operation, effectively preventing structural loosening or damage caused by vibration or external impact.

[0061] Specifically, the cross-section of the locking groove 141 can be rectangular or square, and it needs to have sufficient depth and width to accommodate the locking block 22; the edge of the groove can be straight or slightly chamfered to facilitate the insertion and positioning of the locking block 22. The locking block 22 can be a cuboid or square protrusion that matches the locking groove 141, which can be tightly embedded in the groove, and the bottom of the locking block 22 is connected to the body of the fixing clip 2 to form an integral structure to enhance the overall strength.

[0062] In a preferred embodiment, the locking groove 141 can be a magnetic groove provided on the connecting arm 14, and the locking block 22 is also designed to be magnetic, so that it can be attracted and fixed by the locking groove 141. This design can increase the connection stability between the fixing frame and the connecting arm.

[0063] The assembly and disassembly process of the fixing clip 2 and the connecting wall is as follows:

[0064] The operator only needs to align the locking block 22 on the fixing clip 2 with the locking groove 141 on the connecting arm 14, and then push gently to achieve a secure connection between the fixing clip 2 and the bracket 1. Similarly, the disassembly process is also extremely simple; with just a little pulling force, the fixing clip 2 can be easily removed from the bracket 1.

[0065] Example 4

[0066] This embodiment is an improvement on embodiment 2.

[0067] like Figures 1-7 As shown, in this embodiment, each of the connecting arms 14 is provided with a plurality of flow guide grooves 142, and the opening on one side of the flow guide groove 142 is oriented toward the snap-fit ​​position.

[0068] The design of the airflow channel 142 helps guide airflow within the bracket 1, especially since the opening of the airflow channel 142 is oriented towards the snap-fit ​​position, i.e., the area where the fins 3 are located. This layout increases the airflow area around the fins 3, thereby improving heat exchange efficiency and enhancing the overall heat dissipation effect of the radiator. The airflow channel 142 also reduces the generation of localized hot spots during radiator use; this uniform airflow distribution improves the heat dissipation efficiency of electronic components.

[0069] Specifically, the cross-section of the flow guide 142 can be circular, rectangular, or other shapes. The arrangement of the flow guide 142 on the connecting arm 14 can also reduce the material used in the heat sink and improve the stress condition of the connecting arm 14.

[0070] In a preferred embodiment of this invention, a partition 143 is formed between two adjacent flow channels 142, and the partition 143 is provided with the locking groove 141.

[0071] The locking groove 141 provided on the partition 143 provides more positions for the installation of the fixing clip 2, thereby making the heat dissipation adjustment range of the radiator larger and applicable to more occasions.

[0072] More preferably, multiple flow channels 142 can be provided, so the partitions 143 also form multiple layers, which provides different installation positions for the fixing clips 2. The partitions 143 of different heights correspond to the fins 3 of different heights to meet the heat dissipation requirements of different electronic devices.

[0073] Example 5

[0074] This embodiment is an improvement on embodiment 2.

[0075] like Figures 1-7 As shown, in this embodiment, the base plate 11 is provided with a cooling hole 12, which corresponds to the first slot 15 and penetrates the base plate 11 along the length direction of the first slot 15.

[0076] The cross-section of the cooling hole 12 can be circular, rectangular, elliptical or other shapes.

[0077] The design of the cooling holes 12 corresponding to the first slot 15 can effectively guide airflow and form a good airflow circulation below the first slot 15. By introducing the cooling holes 12, the heat exchange area between the radiator and the surrounding environment is increased, the heat exchange efficiency is improved, and the temperature of the base plate 11 and the surrounding area can be effectively reduced, thereby improving the heat dissipation capacity of the radiator.

[0078] In one embodiment, the cooling holes 12 should be evenly distributed on the base plate 11 to ensure uniform airflow and uniform heat dissipation from all parts of the radiator. Specifically, the size and shape of the cooling holes 12 can be adjusted according to different requirements.

[0079] Example 6

[0080] This embodiment is an improvement on embodiment 2.

[0081] like Figures 1-7 As shown, in this embodiment, the base plate 11 is provided with a plurality of screw holes 13, the screw holes 13 are located on the edge of the base plate 11 and on one side of the connecting arm 14; the edge of the screw holes 13 is provided with a chamfer.

[0082] Screws are used to secure the radiator. Screw holes 13 are located on the edge of the base plate 11 and close to the connecting arm 14. This helps to evenly distribute the force on the base plate 11 when the radiator is secured with screws, enhancing the structural stability of the entire radiator. The chamfered design reduces stress concentration at the edge of the screw holes 13, preventing material fatigue or damage caused by stress concentration and extending the service life of the radiator.

[0083] In one embodiment, the length direction of the base plate 11 is the same as the length direction of the heat sink. Connecting arms 14 are located at the edge of the base plate 11 along its length direction. Three screw holes 13 are provided on each side of the base plate 11 along its length direction, and these three holes are evenly distributed along the width direction of the base plate 11 to ensure uniform force distribution during installation. The heat sink is fixed to the desired installation position by screws passing through the screw holes 13.

[0084] More preferably, the chamfer of the screw hole 13 is 45 degrees and the side length is 0.5 mm.

[0085] Example 7

[0086] This embodiment is an improvement on embodiment 1.

[0087] like Figures 1-7 As shown, in this embodiment, several fixing clips 2 are provided on the bracket 1. Each fixing clip 2 includes a clamping strip 21 and multiple protrusions 23. The multiple protrusions 23 are arranged on the clamping strip 21 along the length direction of the fixing clip 2, and a second slot 24 is formed between two adjacent protrusions 23. The cross-sectional area of ​​the side of the protrusion 23 away from the clamping strip 21 is smaller than the cross-sectional area of ​​the side closer to the clamping strip. That is, the opening between two protrusions 23 is larger. This design facilitates the snapping of the fins 3 into the second slot 24 during assembly. Furthermore, when the fins 3 are inserted into the second slot 24, the shape of the protrusions 23 helps to firmly hold the fins 3 in place, preventing the fins 3 from loosening or falling off under vibration or other external forces.

[0088] By setting multiple protrusions 23 on the fixing clamp 2, the contact area with the heat dissipation fins 3 can be increased, thereby improving the fixing stability of the heat dissipation fins 3 and ensuring that the fins 3 will not loosen or fall off under various working conditions.

[0089] In practical applications, the cross-section of the protrusion 23 can be conical or trapezoidal. It should be noted that the protrusion 23 and the clamping strip 21 are an integral design.

[0090] Example 8

[0091] This embodiment is an improvement on embodiment 1.

[0092] In this embodiment, a specific implementation of the fin 3 is provided, as follows:

[0093] like Figures 1-7 As shown, along the direction from the first slot 15 to the first slot 15, multiple arc surfaces 31 are provided on both opposite sides of the fin 3.

[0094] The design of the arc surface 31 increases the surface area of ​​the fin 3, thereby increasing the area in contact with the air. This helps to enhance heat exchange efficiency, allowing heat to be transferred from the electronic components to the fin 3 more quickly and ultimately dissipated into the environment. Furthermore, the shape of the arc surface 31 helps to optimize the dynamic characteristics of airflow through the fin 3, reducing airflow resistance and allowing air to flow more smoothly over the fin 3, thus improving heat dissipation efficiency.

[0095] In practical applications, the height direction of the fins 3 is the same as the height direction of the radiator, and multiple arc surfaces 31 are set along the height direction of the fins 3 to maximize the surface area of ​​the fins 3 and increase the heat dissipation capacity of the radiator.

[0096] In this embodiment, a fixing surface 32 is provided at the junction of the fin 3 and the first slot 15, and at the junction of the fin 3 and the second slot 24. The fixing surface 32 is a plane.

[0097] A heat dissipation pipe 4 is provided in the first slot 15. The heat dissipation pipe 4 is snapped into the first slot 15 to limit the position of the fin 3.

[0098] By providing a fixing surface 32 at the junction of the fin 3 and the slot, the contact between the fin 3 and the slot can be made more stable, reducing the displacement of the fin 3 due to vibration or thermal expansion and improving the overall stability of the heat sink. Specifically, the height of the fixing surface 32 can be greater than or equal to the height of the first slot 15, thereby improving the installation stability of the fin 3.

[0099] The heat dissipation pipe 4 is snapped into the first slot 15, limiting the position of the fins 3 and ensuring that the fins 3 will not shift or fall off during use. Air can also circulate inside the heat dissipation pipe 4, which improves the heat dissipation capacity of the radiator. The heat dissipation pipe 4 is a hollow pipe.

[0100] Example 9

[0101] This embodiment provides the assembly process of the heat sink of this application, as detailed below:

[0102] like Figures 1-7 As shown, first, prepare bracket 1, fixing clip 2, fins 3, heat dissipation pipe 4, and any necessary fasteners. Place bracket 1 in the predetermined position, ensuring it is stable and level. Bracket 1 can be directly fixed to a wall, ground, or equipment. Specifically, bracket 1 can be fixed to the mounting surface by screws passing through screw holes 13.

[0103] Then, attach the fixing clip 2 to the bracket 1 according to the designed position. This secures the fixing clip 2 through the locking block 22 and the locking groove 141. Place the heat dissipation pipe 4 in the first slot 15 according to the design requirements. Ensure that the heat dissipation pipe 4 is correctly engaged and will not move or fall off during the installation of the fins 3.

[0104] Insert the bottom of fin 3 into the first slot 15 and the top into the second slot 24. Then gradually push fin 3 along the length of the first slot 15 so that fin 3 is completely locked in the locking position.

[0105] Adjust the number of fins 3 according to the required heat dissipation. Repeat snapping the fins 3 into the snap-fit ​​positions until the required number of fins 3 is achieved. After assembly, test to ensure all components of the heat sink are correctly installed and functioning properly. Check for any loose parts or areas requiring adjustment. Thermal grease can also be applied between the fins 3 and the heat pipes 4 to improve the heat sink's heat dissipation capacity.

[0106] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0107] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0108] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
